"Congratulations!" it told me.
Registration opened Monday for the fall marathon I intend to run, so I'm sure soon enough my e-mail will congratulate me for that, too.
I just don't know if "congratulations" is the right term to be used in this scenario. More like, "Good job, you dropped 'X' amount of dollars to run until utter exhaustion. Here, have a banana when you're finished."
I'll have them know I don't like bananas.
